Connecting joint of prefabricated reinforced concrete column and construction method
The invention provides a connecting joint of a prefabricated reinforced concrete column and a construction method. The connecting joint is composed of a lower column, an upper column, a sleeve, a stirrup and fine aggregate concrete, wherein a boss at the bottom of the upper column is inserted into a groove in the top of the lower column; a lower longitudinal rib of the lower column and an upper longitudinal rib of the upper column are sleeved with the sleeve, and the lower longitudinal rib and the upper longitudinal rib are clamped by the sleeve; the stirrup is hooped on the sleeve and the upper longitudinal rib of the upper column; and a concave space formed by the lower column and the upper column is filled with the fine aggregate concrete. In the construction process, after the boss of the upper column is inserted into the groove of the lower column, the upper longitudinal rib of the upper column is sleeved with the sleeve upwards, then the upper column slowly falls down, a formwork with a horn mouth is fixed to the lower column, the fine aggregate concrete is poured, and finally redundant overhanging concrete is cut off. The connecting joint is simple in structure, reliable in force transmission, convenient to construct and capable of meeting the stress and construction requirements of a fabricated building.
一种预制钢筋混凝土柱的连接节点及施工方法，由下柱、上柱、套筒、箍筋和细石混凝土组成；上柱底部的凸台插到下柱顶部的凹槽内；套筒套在下柱的下纵筋和上柱的上纵筋上，套筒卡住下纵筋和上纵筋；箍筋箍在套筒和上柱的上纵筋上；下柱和上柱形成的凹形空间填有细石混凝土。施工过程中，上柱的凸台插到下柱的凹槽后，将套筒向上套在上柱的上纵筋上，再缓慢落下上柱，将带有喇叭口的模板固定在下柱上，浇筑细石混凝土，最后将多余的外伸混凝土切除。本发明的连接节点构造简单、传力可靠、施工方便，能够满足装配式建筑的受力和施工要求。
